 his constellation of endocrines, in spite of mishaps, not at all or

formation has been sufficiently deep, and shaken the very 

 constitution of his germ-plasm. So family dispositions and

Hormone reactions, as we have seen, initiate the complicated 

 forces, processes and expressions of sex. The dictum of the 

 founder of modern pathology, Virchow, that Woman was in effect 

 an appendix to the ovaries, has long been taken to apply to her 

 psychic traits as well as somatic. Her mind, like her skin, her 

 hair and her pelvis, is a product of the ovarian endocrines. But 

 these determinations are by no means her monopoly. M

 springs within springs that are his glands of internal secretion.

 two reasons. First, the male sex hormones have not the ii
